Hi,
I analysed osgVisual (and in comparison, osgviewer) with the debug build of
openscenegraph.
I fixed my memoryleaks, but these memory leaks are still existing in osgVisual
but not with osgviewer (both cow.osg).
At the moment I don't know how to proceed, so if someone has an idea, I'm open
minded :)
Otherwise I'll stop hunting these memory leaks, less than 1 kB is not so much..
;)
